Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77400, here are decompositions:
- 17 + 77383 = 77400
- 23 + 77377 = 77400
- 31 + 77369 = 77400
- 41 + 77359 = 77400
- 53 + 77347 = 77400
- 61 + 77339 = 77400
- 83 + 77317 = 77400
- 109 + 77291 = 77400
Showing the first eight; more decompositions exist.
